vDAvID GREEN, F GREENEIELD, NEW YORK.

.APPARATUS Foa PEEVENTING CATTLE PROM GETTING oNTo EAILROADS.

Specification of Letters Patent No. 895, dated August 2 5,

To all whom it may concern.' e

Be it known that I, DAvInGREEN, of

Greenield, in thecounty of Saratoga and State of New York, have inventeda new and usefulmode of preventing cattle and other animals from gettingonto railroads and also to prevent them from getting into other roads orinclosures; and I do hereby declare that the following is an exact description.

The nature of my invent-ion `consists in attaching to a railroad theleverA A, (see drawing) parallel to railroad and at right angles tolever B B, to which it is firmly attached at point V(C) a gate L L,vwhich is opened bycar wheels M lVI, bearing on A A, which moves downand raises the long part of B B, hung at point (Z2) which draws o-n cordC C C, passing under pulleys D and E attached to gate at point (a) anddraws gate back near pulley Pulley F takes effect by co-rd Gr G, a shortdistance before gate arrives at or near pulley E, pulley H, by cord I I,at a less distance and prevents a part of its concussion and assistsgate to return to its position on railroad; Protection J J, protectslever A A, and supports railroad. Safety frame K K, should protect mostof machinery.

Length of AA, and also when A A, be

elevated should be sloped from top rail at each end toward center inproportion to greatest velocity run on railroad where it may be applied.A A, should be elevated toward center when gate be shut in proportion tolength of lever B B. It should be beveled from top of protect-ion` andrail to its top (when gate be shut) to prevent friction when moving downand to insure its returning to its former position, when it is down itbears on ties of road or pieces attached for that purpose. Its ends areprevented from rising above railroad by protection. A A, may be made ofiron or wood. When made of iron it may be composed of pieces connectedwith screws or bolts or by any other means by whichV itmay be mostIirmly attached or made of one piece. When construct-ed of wood theremay be plates of iron attached totop, sides and bottom or only on topside or bottom as thecase may require making it sutliciently strong andpreventing its springing in av horizontal or vertical direction.

Lever B B, is permanentlyV attached fo AA, at point (C) at right anglesand has a fulcrum or bolt through it and is hung in an iron orvtimberpostfastenedto ties of board or timber placed for that purpose atr asufcient distance from connection to raise the longerpart of `B B. lhen`car passes on to A A, a rope or chainis attached at or near the end ofthelonger part of B B,

which passes under pulleys D and E, thence to point (a) in back part of.gate and `draws gate open when car bears on AA. B B may Y be made ofwood or iron.

Protection J J should be-the largest at ends by taking out a piece fromside nearest road and near ends to center, or attaching pieces to theabove named side at ends leaving space in width between protection andfi rail sufficient for A A, Vto move in and of less length than lever AA, to receive the ends of A A, sufficient to prevent the lower part of AA from rising above railroad;

The parts of protection that receive the ends i i of A A, should besloped from topto bottom toward ends, and A A, should be simil larlysloped from points on top where protection .project-s to ends, so as toadmit of A A being suiiiciently elevated, or lever` A A may have at theabove named points near the ends pieces taken out to the ends and nearits bottom and also protection should have similar pieces taken out frombottom near the top to admit of the afore named points rising to surfaceof roads. When A A, be elevated, protection should be firmly attached atends to sill of rail road and also to ties of road by gains being cut orbolts or iron knees bolted on to ties to secure protection fromspringing laterally. i Y

Protection may touch outside of A A, when A A be elevated and lie levelwith rail road..

It maybe made of wood and have wear irons attached to inside to preventfriction when A A moves down and serve to direct A in its movement. tGate may be made and braced in any of*` the approved modes of making andbracing i gates except its back must be higher and wider than forepart,to admit of fore part passing through its place. It must be hung on afulcrum or bolt near the bottom` of gate of suflicient lengthto admit ofbracing gate from toward each end of bolt. hung a sufficient distancefrom rail road in safety frame and made long enough to leave V i i 110space "for car to pass through when gate be open. v

Two gates may be applied to rail readin- It should be stead ofone andhung as the above mentioned gate a sulicient distance from road at eachside of road kand but half as long as the above named gate and meet incenter of road When shut With the aforementioned machinery attached to'each side of road to effect their opening and shutting.

Cords over pulleys F and H7 by the eect of their Weights lessen theconcussion when gategoes back insures its shutting and prevents a partof its concussion in shutting and assists in giving first impulse toopen when shut. Pulleys may be made of iron or Wood and move in blocksto keep cords in their proper places.

The above mentioned gate or gates may be applied toother and commonroads With the aforementioned machinery by placing leverV A A, inavgroove or-'by hav-ingAA A,

niV ade larger than said groove7 and' When ele` vated touch under sideof said grooveV Y or Jtimbers that said groove is constructed with,which common carriagey Wheels may be conducted in. Safety frame K K,should be inclosed leaving space for gate Vand lever Gr G, to move in.

What I claim as my invention and desire .to secure Vby Letters Patentis- The application ofv the afore mentioned gate or `gates and machineryto railroads other roads and places WhereA they may Vbe used.

DAVID GREEN.
